    Jack Allen's questions to Allogene Therapeutics (ALLO) leadership • Q2 2025

    Question

    Jack Allen of Baird asked about the confidence in the durability of remissions based on MRD conversion, and what patient numbers might be expected in the ALLO-329 autoimmune disease data readout next year.

    Answer

    CMO Dr. Zachary Roberts expressed confidence that MRD conversion is a strong correlate for long-term disease control based on growing data in the field.

    Question

    Representing Jack Allen, Nick asked about the potential impact of the new CBER Director on the broader autoimmune opportunity for cell therapies.

    Answer

    CEO David Chang expressed confidence, emphasizing that the FDA is an institution that follows established guidance. He differentiated autoimmune trials from oncology, noting their endpoints are based on symptom improvement, not overall survival. He does not foresee new hurdles for advancing CAR T in autoimmune diseases, provided the safety and efficacy data are strong.

    Jack Allen's questions to Allogene Therapeutics (ALLO) leadership • Q4 2024

    Question

    Jack Allen from Baird requested details on the ALPHA3 futility analysis, asking if it's a comparison against the control arm or a hurdle rate, and which metrics like MRD conversion or response rates would be used.

    Answer

    Dr. David Chang, President and CEO, clarified that it is a standard futility analysis assessing the totality of data. The key efficacy metric will be the MRD conversion rate, with the expectation of a significantly higher rate in the treatment arms compared to the observation arm. Safety will also be assessed for balance across arms.

    Jack Allen's questions to Allogene Therapeutics (ALLO) leadership • Q3 2024

    Question

    Jack Allen asked for an update on the ALPHA2 study in CLL, including its status and go-forward path. He also inquired about the durability bar for the ALLO-316 program in RCC compared to the existing standard of care.

    Answer

    Dr. David Chang, President and CEO, confirmed the CLL study is ongoing but is subject to a pipeline prioritization, with ALPHA3 and ALLO-329 being the top priorities; an update is planned for next year. Dr. Zachary Roberts, EVP of R&D and CMO, explained that for ALLO-316, the durability bar is quite low, as third-line RCC therapies offer modest PFS of only a few months with continuous treatment. He noted the RMAT designation and high investigator enthusiasm support the program's potential.

    Question

    Jack Allen from Baird inquired about the standard deviation observed in the blinded ORBIT trial data, confidence in the statistical analysis plan (SAP), and whether there were any plans to present updated data from the Phase II cetrusumab cohort.

    Answer

    Emil Kakkis, Founder, President & CEO, did not provide the standard deviation but acknowledged significant variation. He expressed confidence in the negative binomial model used in the SAP, noting it's the best method for fracture data and allows for co-variables to manage variation. He also stated there are no specific plans yet to present updated Phase II data.

    Question

    Jack Allen asked for clarification on how many patients in the setrusumab trial had 12 months of data at the first interim readout and inquired about any disclosures regarding the drug's impact on bone pain.

    Answer

    CEO Emil Kakkis explained that due to a 'hockey stick' enrollment pattern, the vast majority of patients had less than one year of data at the first interim. CMO Eric Crombez added that while they are formally tracking pain, they have heard significant anecdotal reports of pain improvement from the Phase II study. Kakkis noted that, similar to Crysvita, patients feeling better and becoming more active is a powerful, tangible benefit that drives enthusiasm for the therapy.

    Question

    Jack Allen requested more context on what triggers the setrusumab interim analyses, asking if the timing is now fixed or still dependent on accruing fracture events.

    Answer

    CEO Emil Kakkis clarified that the interim analyses are now set on a fixed timeline (year-end/early 2025 and mid-2025). He explained this was an operational choice to simplify planning, as the original event-based trigger was challenging. The timeline was set by estimating when fracture event milestones would be hit, and they are confident the actual fracture rate will be sufficient by those dates.

    Jack Allen's questions to Cellectis (CLLS) leadership • Q2 2025

    Question

    Jack Allen from Baird questioned the bar for success and durability expectations for UCART22 in relapsed/refractory ALL, inquired about the company's view on Allogene's move away from CD52 lymphodepletion, and asked about infection risk mitigation strategies.

    Answer

    Chief Medical Officer Dr. Adrian Kilcoyne stated that durability is critical and regulators have agreed on the use of short-term surrogate endpoints for the primary analysis, with more details to come at the R&D Day. Regarding Allogene, both Dr. Kilcoyne and CFO Arthur Stril emphasized that Cellectis's situation is different due to product positioning, lower dosing, and the use of actual alemtuzumab from Sanofi, making comparisons difficult. Dr. Kilcoyne also noted that mandatory prophylaxis is already built into trials to mitigate infection risk.

    Question

    Jack Allen asked about Cellectis's internal success criteria for the UCART22 readout, the clinical timeline for AstraZeneca programs, the novelty of their targets, and any updates on the Servier arbitration. He later followed up on the Servier litigation, the implications of CARGO's discontinued CD22 asset, and the durability data from Allogene's cema-cel program.

    Answer

    CEO Dr. André Choulika expressed confidence in the UCART22 data for the heavily pretreated patient population. CBO Arthur Stril noted the AstraZeneca collaboration is progressing well across multiple therapeutic areas with potential data this year, but declined to comment on the ongoing Servier arbitration. Regarding CARGO's discontinuation, Stril and CMO Dr. Adrian Kilcoyne viewed it as confirmation of the market need for non-CD19 therapies and stated the toxicity issues are not inherent to the CD22 target. Stril also highlighted Allogene's cema-cel data as very encouraging for the durability of allogeneic platforms.

    Jack Allen's questions to Lineage Cell Therapeutics (LCTX) leadership • Q4 2024

    Question

    Jack Allen of Robert W. Baird & Co. asked about Lineage's strategy to protect its market leadership in RPE cell replacements amid a growing competitive landscape. He also inquired about the timeline for the updated 3-year OpRegen data and how positive RPE results serve as a proof of concept for the broader Lineage platform, including OPC1.

    Answer

    CEO Brian Culley emphasized that Lineage's competitive advantage is a "triumvirate" of its advanced manufacturing, Genentech's development expertise, and Roche's commercialization leadership. He stated that while Genentech controls the timing of the 3-year data release, the positive effects have been confirmed to persist. Culley positioned non-oncology cell therapy as a major growth area, suggesting that successes in RPE transplants validate the cell replacement approach for other conditions like spinal cord injury.

    Answer

    CEO Brian Culley stated he was unable to comment on the specifics of the RMAT submission or future data release timelines, as those are controlled by their partner, Roche/Genentech. He speculated that a large Phase IIb study, similar to Iveric's strategy, could serve as a registrational trial for OpRegen. He also confirmed that natural hearing regeneration occurs in species like birds, which serves as a scientific precedent for the ANP1 program's approach.

    Jack Allen's questions to Lineage Cell Therapeutics (LCTX) leadership • Q2 2024

    Question

    Jack Allen of Robert W. Baird & Co. questioned the timing for accessing CIRM grant capital after IND clearance and asked about the OpRegen Phase I/II patient follow-up. Specifically, he asked about the rationale for extending the follow-up to a total of 10 years, rather than the 15 years sometimes guided by the FDA for cell therapies.

    Answer

    CFO Jill Howe explained that accessing CIRM funds would be a gradual process, not a lump sum, and may see delays due to a high volume of applications at CIRM. CEO Brian Culley addressed the follow-up extension, stating the original FDA-cleared protocol was for five years. He speculated that Genentech's interest in a 10-year total follow-up is to assess the long-term durability of the treatment, a key factor for its value proposition, rather than a new regulatory requirement for this specific program.
